Title: Magnetic disc recording device
Inventor: MIWA TAKAHIRO
IPC: G11B5/02
Filed: 1984-06-23
Abstract: PURPOSE:To prevent mixture of a previously written signal by moving a single gap head successively to erase signals in both side edge parts of a track after the single gap head is positioned to the designated track to record an information signal on a magnetic disc. CONSTITUTION:After write, a computer 50 drives a pulse motor 30 again to move a magnetic head 20 to one side position, and the information signal on the surface of a magnetic disc 16 corresponding to the position of the magnetic head 20 is erased. At this time, the magnetic head 20 is moved by an extent corresponding to the rotation of the pulse motor 30 due to two-pulse driving signal input and is moved to one side by a half of a pitch l on the surface of the magnetic disc 16. An erasing signal is supplied to the magnetic head 20 from a head reproducing/recording circuit 56 for a period longer than the time when the magnetic disc 16 is rotated once at least. Next, the magnetic head 20 is moved to the other side of the designated track, and the information signal on the surface of the magnetic disc 16 corresponding to the position of the magnetic head 20 is erased.

IPC: G01N29/04
Filed: 1979-10-08
Abstract: PURPOSE: To enable the quality inspection of a sample possible to contact because of high temperature or high speed by a method wherein an ultrasonic wave pulse is excited at one surface of a sample and the arrival of the pulse at the other surface is inspected in a noncontact way.  
     CONSTITUTION: A pulse laser lifht L 1  of high output with a short time radiation is projected from a pulse laser 2 onto one surface 1a of a sample 1 of a thickness d. A micro segment of the laser light L 1  is taken out by means of a beam splitter 3 and it is projected to a light detector 4. The laser light L 1  which is projected to the sample surface 1a at the time point t=0, hits the surface to generate an ultrasonic pulse wave, and this ultrasonic wave propagates in the sample 1, reaches the other surface 1b of the sample at the time point t=t to generate a vibration displacement Z on the surface 1b. A vibration displacement detector 5 detects this displacement Z, For example, the laser light on the measurement surface is split by means of a beam splitter and one of the split laser light is projected to the sample surface 1b and the other is projected to a mirror, and then, both reflection lights are led to a common light receiving unit, and they are detected by means of a detection coil arranged against the sample surface to measure a displacement.

Title: Sheet processing device and image forming device
Inventor: WATABE TOMOYUKI
IPC: G03G15/00
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To surely stack and match first and second sheets in ejection of them by turning a downstream ejection roller by a predetermined quantity in the direction reverse to the ejecting direction in response to an opening/closing action of an oscillational guide and fixing this roller according to the open/close position of the oscillation guide. SOLUTION: When an action gear 46 is turned in the direction shown by the arrow, a projection part 46b pushes up an openable arm 47 installed on one side of an oscillational guide 20 so as to open an oscillational guide 20. When the action gear 46 is turned further, the oscillational guide 20 starts to close, and subsequently, engagement between the projection part 46b and the openable arm 47 is released when the action gear 46 is turned further, so that the oscillational guide 20 is dropped by its self-weight and closed. After a motor closing the oscillational guide 20 is started, the oscillational guide 20 is closed at a high speed to a predetermined position, however, when the guide 20 is closed to the predetermined position, a motor output is changed so as to slow down a closing action.  When the oscillational guide 20 is closed further to the next predetermined position, the motor output is changed again so that the motor drive is stopped after closing is detected. A bundle of sheets on a staple tray are bound while clamped between a pair of downstream ejection rollers.

Title: Station search device for television receiver
Inventor: NISHI MASAHIRO
IPC: H04N5/44
Filed: 1981-08-19
Abstract: PURPOSE:To start of a station to be searched from a minimum tuning voltage, by changing a band to the VHF-LOW, after reaching a maximum tuning voltage of a UHF band, when an automatic station research operation is executed, while a TV station of the VHF-LOW band received at a minimum tuning voltage is under broadcasting. CONSTITUTION:When a TV signal possible for the reception with a minimum tuning voltage (m) at the VHF-LOW band is inputted to an antenna input, a changeover switch 28 is closed and a trigger switch 27 is further turned on with the state of j=+B, the state of i=+B is instantly obtained to bring an automatic station search processing circuit 32 into the station search state. Thus, a signal (l) and the tuning voltage (m) are increased and the system stops by catching the TV signal, but a pulse of i=+B is applied on each occasion to obtain the station search operation. When the tuning voltage (m) reaches the maximum UHF, the station search operation is stopped, and setting of l, m=minimum and band=VHF-LOW is made. Thus, the (i) changes to L. In this case, since the inputs (j) and (i) of the circuit Q go to H and L respectively, a transistor 41 turns on and the state of i=L is obtained, then AFT information (d) and (e) go to H. When a station search trigger is applied next, the station search is obtained from the turning voltage (m) from the minimum value.

Title: Gas filling method for dry variable capacity gas holder and movable gas sealing device
Inventor: KANEKO TADAO
IPC: F17B1/12
Filed: 1985-06-18
Abstract: PURPOSE:To contrive to lighten a fender device by so designing a gas holder that a force caused by a pressure inside a gas holder and acting on the outside of the side wall of the fender device may not exceed a force caused by a gas pressure and acting on the inside of the side wall over all the period when pressured gas is filled into the gas holder. CONSTITUTION:When supply of pressured gas is continued, a fender device 22 is raised and though a force acting on the inside of a corrugated plate 40 doesn't change, a force acting on the outside of the corrugated plate 40 is reduced. That is, a rise of the fender device 22 causes itself to part from an outer seal 24 gradually toward the upper part of the outside of the corrugated plate 40 and this section comes to be out of application of a gas pressure. Consequently a force acting on the inside of the corrugated plate 40 becomes larger than that acting on the outside. A cylindrical structure is stronger against internal pressure than against external one, so the thickness of the corrugated plate 40 can be made thinner in comparison with any conventional fender device.
